Official Luthiers Forum!

I was going through my guitar tool drawer and came across this (picture below). All was sealed in a plastic bag including the instruction sheet. Now, I know what a saddlematic is. And none of this appears in the manual. What is this tool set?

Mike

Methinks you've used the old bag to put some random stuff in...

Nope. It was sealed until tonight.

Looks like the bridge pin hole chamfering tool.

That looks like a plug cutter and drill stop....

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Bridge hole chamfering tool, definitely

Clear sign of Tool Acquisition Syndrome

I have that little tool and it works very well for me.

Me too. I used mine the other day on a rosewood bridge. The pilot keeps the tool centered on the hole and it cuts cleanly. I use my grandpa's very old hand cranked hand drill which gives good control.

Now I understand why I cant locate the saddle with that tool.
Neither will the saddlematic chamfer holes!
Mike, are you buying tools and just throwing them in a drawer without even trying them out?
You do have TAS.

This is indeed a symptom of TAS. I don't have it as bad as I used too. Back in the day, I was a sorry case. Thanks for the ID. Maybe I will try it out for the intended purpose. I have 5 bridges waiting for chamfers.

I really like the tool.

Can I use it on a drill press? I don't have any directions.

Oops. I see someone posted instructions above. But, experiences are welcome

I'm getting clean chamfers effortlessly with a small cordless drill.
Depth stop may polish the top of the bridge but does not damage it.
Rather than setting the depth stop just with the grub screw as per instructions, I fitted some 10 x 16 x 0.3 mm shim washers behind brass/plastic stop against shoulder of cutter to give consistent diameters at top of chamfer (I use 2 or 3)
Useful if you disassemble to clean the tool as it goes back to exactly the same setting and there's no chance of the grub screw slipping during use.

I really like this tool. Very nice chamfers.

Maybe it would be worth digging through your tool drawer again to see what else turns up.

I think you are right. After these builds I'm having a shop clean out and reorg. There was a time when all I did was hang out in the classifieds here and in other sites. You wouldn't believe the stuff I bought over at sawmill creek. I don't know what that chamfer tool costs, but I recommend it. Way better than the typical chamfer tool u can get at big box.

I do have a question about that stepped drill bit for tuner installs. Will it work for Gotohs? Are there industry standards for tuner posts? I'm tired of the setup require to swap out bits and set depths

I have a couple of those, I found you have to look at the spec for the tuner. They make a few different ones.

I found another sure fire way with normal bits. Drill a small pilot hole all the way through. On the top drill with the right size bit for the bezel the correct depth, then change to the shaft bit and drill through. The pilot hole keeps things centered.

I just finished installing a set of Gotoh M6 style tuners a few minutes ago. This was the first time for me making the tuner holes using a brad point bit to drill a pilot hole followed by StewMac's rear peghole reamer which leaves a step down in diameter for the tuner post (I used the drill press for both). I don't know if these tuners or the tool are the same as you have in mind, but the reamer worked as advertised.
